Still though, add an intercooler and that 58 HP gain will jump a bit more. The truely sad part is that $5,000 price tag. Corksport says theirs will be with no intercooler, but only $1,800..Makes ya wonder....
I think at this point all you really have to do is just sit tight and wait for the kits to come out and take your pick. Or go the straight custom route like SpoolinMP3. Personaly I'd go for a supercharger. Not as big of gains, but more hassle free, and it's power is available all over the powerband.
